you would have to go and see about being regressed by a hypnotist if you want to find anything out like that. Go along to a local spritualist church and they might help you with the information you need.Other than that, have a look in the yellow pages! lol not sure what it would be under though! Or you could even use the net. In fact thats probaly your best bet.
personally its not something i would fancy and it amazes me how people are always egyptian queens or one of King Arthur's knights, something along those lines, never joe Bloggs from manchesters backstreets. lol
and btw, JL, hang your head in shame, that is a very old joke! :-)
